pcie_host: verify mmcfg address range

For a conventional pci device behind
a pcie-to-pci bridge, pci_host handlers get confused by
an out of bounds access in the range [256, 4K).

Check for such an access and make it have no effect.

pci: Common overflow prevention

Introduce pci_config_read/write_common helpers to prevent passing
accesses down the callback chain that go beyond the config space limits.
Adjust length assertions as they are no longer correct (cutting may
generate valid 3 byte accesses)....

pci: use devfn for pci_find_device() instead of (slot, fn) pair

(slot, fn) pair is somewhat confusing because of ARI.
So use devfn for pci_find_device() instead of (slot, fn).

Add endianness as io mem parameter

As stated before, devices can be little, big or native endian. The
target endianness is not of their concern, so we need to push things
down a level.

This patch adds a parameter to cpu_register_io_memory that allows a
device to choose its endianness. For now, all devices simply choose...

pci: rename (pci_/pcie_mmcfg_)addr_to_dev

This patch renames pci_addr_to_dev(), pcie_mmcfg_addr_to_dev()
to pci_dev_find_by_addr(), pcie_dev_find_by_mmcfg_addr()
as "Michael S. Tsirkin" <> suggested.

pci: simplify (pci_/pcie_mmcfg_)data_read()

Remove switch on length: we don't care about
high bits for value, so just return all ones
if no device. And add one assert().

pci: pcie host and mmcfg support.

This patch adds common routines for pcie host bridge and pcie mmcfg.
This will be used by q35 based chipset emulation.
